Finish bumping stage0
It looks like the last time had left some remaining cfg's -- which made me think
that the stage0 bump was actually successful. This brings us to a released 1.62
beta though.
This now brings us to cfg-clean, with the exception of check-cfg-features in bootstrap;
I'd prefer to leave that for a separate PR at this time since it's likely to be more tricky.

Prepare Rust for opaque pointers
Fix one codegen bug with opaque pointers, and update our IR tests to accept both typed pointer and opaque pointer IR. This is a bit annoying, but unavoidable if we want decent test coverage on both LLVM 14 and LLVM 15.
This prepares Rust for when LLVM will enable opaque pointers by default.
Move download-rustc from python to rustbuild
- Remove download-rustc handling from bootstrap.py
- Allow a custom `pattern` in `builder.unpack()`
- Only download rustc once another part of bootstrap depends on it.
This is somewhat necessary since the download functions rely on having a full
`Builder`, which isn't available until after config parsing finishes.
Helps with https://github.com/rust-lang/rust/issues/94829.

ptr::invalid is not equivalent to a int2ptr cast
I just realized I forgot to update these docs when adding `from_exposed_addr`.
Right now the docs say `invalid` and `from_exposed_addr` are both equivalent to a cast, and that is clearly not what we want.

Make some tests check-pass
This touches the tests related to lint, parser, and importing, all of them should be fine with `check-pass`.
r? ``@compiler-errors``
Remove FIXME on `ExtCtxt::fn_decl()`
`ExtCtxt::fn_decl()` is used like `self.fn_decl(..)` or `self.cx.fn_decl(..)`, coverting it to an assoc fn, for example, makes it inconvenience (e.g. `self.cx.fn_decl(..)` would be longer to represent). Given that, it doesn't seem a "FIXME" thing and unused `self` is okay, I think.
Add support for embedding pretty printers via `#[debugger_visualizer]` attribute
Initial support for [RFC 3191](https://github.com/rust-lang/rfcs/pull/3191) in PR https://github.com/rust-lang/rust/pull/91779 was scoped to supporting embedding NatVis files using a new attribute. This PR implements the pretty printer support as stated in the RFC mentioned above.
This change includes embedding pretty printers in the `.debug_gdb_scripts` just as the pretty printers for rustc are embedded today. Also added additional tests for embedded pretty printers. Additionally cleaned up error checking so all error checking is done up front regardless of the current target.

Update to rebased rustc-rayon 0.4
In rayon-rs/rayon#938, miri uncovered a race in `rustc-rayon-core` that had already been fixed in the regular `rayon-core`. I have now rebased that fork onto the latest rayon branch, and published as 0.4. I also updated `indexmap` to bump the dependency.
`Cargo.lock` changes:
Updating indexmap v1.8.0 -> v1.8.2
Updating rayon v1.5.1 -> v1.5.3
Updating rayon-core v1.9.1 -> v1.9.3
Updating rustc-rayon v0.3.2 -> v0.4.0
Updating rustc-rayon-core v0.3.2 -> v0.4.1
Previously whenever a duplicate discriminant was detected for an Enum,
we would print the discriminant bits in the diagnostic without any
casting. This caused us to display incorrect values for negative
discriminants. After this PR we format the discriminant signedness
correctly. Also reworded some of the original error
messages.
update libbacktrace
It seems like previously we were on a tag of the backtrace repo; not sure if there is a policy that it should always be a tag?
